Benefits of technology

This patent describes a thermoplastic resin that has good electrical properties. It is made up of polycarbonate, a flame retardant called cyclic phosphazene, an impact-reinforcing agent, and fluorinated polyolefin. The combination of these ingredients results in a composition that has good electrical insulation, is resistant to fire, and has improved impact strength.

Problems solved by technology

In general, in order to improve the flame retardancy, a phosphorus-based flame retardant may be increasingly used, but it causes to deteriorate heat resistance and impact strength, and accordingly, in order to improve this impact performance, when an impact-reinforcing agent is increasingly used, flame retardancy is deteriorated.

Description

TECHNICAL FIELD[0001]A thermoplastic resin composition having excellent electrical properties and a molded article produced using the same are disclosed.BACKGROUND ART[0002]A polycarbonate resin is an engineering plastic having excellent mechanical strength, high heat resistance, transparency, and the like, and therefore may be used in various fields such as office automation devices, electric / electronic parts, architectural materials, and the like. In the field of electric / electronic parts, a resin used as external components of a laptop and a computer requires high flame retardancy and high strength due to slimming and thinning of TV, a monitor, and a laptop.[0003]In addition, a polycarbonate material used for housing the electric / electronic parts requires excellent electrical properties and impact strength along with the high flame retardancy.[0004]In general, in order to improve the flame retardancy, a phosphorus-based flame retardant may be increasingly used, but it causes to d...
